Weather Briefing

MVFR

Shannon Airport is currently reporting marginal VFR (MVFR) conditions with broken clouds at 2,000 feet and 10 miles or greater visibility.

Wind Analysis

Winds are from the west-southwest (250°) at 15 knots. Runway 24 is favored with a 15-knot headwind and 3-knot crosswind component. Student pilots and low-time aviators should exercise caution.

Visibility & Ceiling

Visibility is unrestricted. The ceiling is 2000 feet AGL (broken), placing conditions in the MVFR category.

Temperature & Moisture

Temperature is 17°C (63°F) with a dewpoint of 14°C. The narrow temperature-dewpoint spread suggests high humidity and potential for visibility restrictions, especially during cooling periods.

Forecast Outlook

The TAF forecast covers the next 24 hours. IFR conditions are expected to persist or develop. An instrument rating and IFR flight plan are recommended. Temporary MVFR conditions are forecast between 13:00Z and 22:00Z. Temporary IFR conditions are forecast between 22:00Z and 05:00Z. There is a 30% probability of MVFR conditions between 05:00Z and 12:00Z.

Pilot Recommendations

VFR pilots should exercise caution. Consider filing IFR if instrument rated, or postponing the flight if conditions are expected to deteriorate further. The narrow temperature-dewpoint spread creates risk of fog formation, particularly during evening and early morning hours. The forecast indicates conditions may deteriorate. Ensure you have fuel reserves and a viable alternate airport.

This briefing is generated from real-time METAR and TAF data. Always verify with official sources before flight.

About Shannon Airport

Overview

Shannon Airport serves as a critical international gateway in western Ireland, located in County Clare. Positioned strategically on the west coast, the airport provides essential connectivity for transatlantic and regional aviation operations. Its large airport classification and substantial 10,495-foot runway support a wide range of aircraft types and operational requirements.

Flying Conditions

Shannon's coastal location at 46 feet mean sea level experiences variable maritime weather conditions typical of Ireland's western region. The airport's long runway (06/24) allows for reliable operations across changing meteorological environments, providing flexibility during challenging wind or visibility scenarios. Pilots should anticipate potential Atlantic weather systems that can generate rapid meteorological changes.

Notable Features

The airport is situated in a relatively flat coastal terrain, with its 52.702000, -8.924820 coordinates positioning it near the Shannon River estuary. The asphalt (ASP) runway surface provides consistent ground handling characteristics. Its western Irish location means potential interactions with maritime weather patterns and associated wind dynamics.

Approach Considerations

The 10,495-foot runway (06/24) offers substantial landing and takeoff capabilities for most commercial and large aircraft. Runway orientation suggests potential crosswind management may be required, particularly given the coastal geographical context. Pilots should prepare for potential wind variability and use the extended runway length to their operational advantage.
